PURPOSE:To perform the best composition of a picture corresponding to the view position of a viewer by calculating the mutual distance between a foreground picture and a background picture and determining the display areas and display magnifications of the respective pictures according to the coordinates of the position of the viewer. CONSTITUTION:The composition of a picture A as the foreground picture and a picture B as the background picture is varied corresponding to the position of the viewer who sees the picture of a CRT 11 so as to give a feeling of stereoscopy to a picture to be displayed on the CRT 11. For the purpose, the pattern recognition of the viewer by a camera 6 and distance measurement by an infrared distance measuring instrument 7 are carried out. Then a picture for the lateral position of the viewer and a picture for the longitudinal position are combined together to generate a composite picture. Further, when the viewer moves forward and backward about the CRT 11, the pictures A and B are enlarged or reduced according to their front-rear directional positions. Consequently, the composite picture varies according to the position of the viewer and stereoscopic display effect is obtained. |
